p To ALL wHoM rr MAY coNcnRN:

Be it known that I, HENRY NEUMEYER, of Millerstown, in the county of Lehigh, and State of Pennsylvania, have invented a new and improved Spiral Hay-Fork; and I do hereby declare that the following is a full, clear, and exact description thereof, which will ena-ble others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of thisspecication, in .which- Figure lis a side view ol' my improved hay-fork, part of the roller or pulley being broken away to show the construction.

Figure 2 is a cross-section of the same, taken through'the line a; w, fig. 1.

Similar letters of reference indicate like parts.

My invention has for its object to furnislran improved hay-fork, simple in construction, easily operated, and effective in its operation; and it Consists of an improved spiral hay-fork, formed by the combination of the i vertical rines, shank, roller or pulley, and one or more spiral tines, rope, lever step, supportiiig-frame, and

spring with each other, as herein more fully described.

A are the vertical tines, the upper parts of which are bent or curved towards each other, and their upper ends securely attached to the lower end of the shank B, as shown in Eg. 1. Upon the upper end of the shank [l B is formed, or te it is4 attached, aringl o1' loop, C, to which is attached the end of the rope by which the forli is raised and suspended. The middle part of the shank B is made round, and upon it is placed a roller or pulley, D, the face of which may be grooved for the reception of the rope E, by means of which the hay is discharged from the fork. The roller or pulley D revolves freely upon the shank B, and to its lower part is securely attached the upper end of the spiral tine F, as shown in fig. l, the lower end of said spiral tine terminating a. little above the lower ends of the vertical tines A, so that the said spiral t-ine may be supported against any w side pressure arising from the unequal balancing of the fork load. The drawings represent only one spiral tine l; F as being attachedto the lower part of the roller or pulley D; butmorethan one may be used if desired. Gr'

is abent arm, frame, or support, attached to the upper end or" the shank B, the lower end of which terminates near the lower part o' the roller or pulley D, as shown in iig. To the upper part of the support G is pivoted the upper end of the lever stop H, the lower end of which passes through, and works in, a slot formed in the lower part of said support, where it isfheld in whatsoever position it may be placed by the pressure of the sinall spring I attached to the lower part of' said support G. Upon the lever stop H is placed av roller, 7L', to relieve the friction of the rope E. l J are stops, attached to the sides of the roller or pulley D, which, when the leve;` stop is pushed town-rds said roller, corne in contact with it, and prevent the pulley from being revolved by the pressure of the hay upon the spiral tine, which might cause the load to be discharged before reaching the required place. E n rope, one end of which is attached to the pulley or roller D 3. thence it passes through a slot in the side of the support G, und passes down into such n position that it. can be readilyT reached bv the operator. lu using the -fork it is placed upon the hay to be raised point downwards. Theil, l y turninvg the roller D, hy means of the small lever or handle K attached to its lower end, the spiral tine F is forced into the hay, the vertical tines A passingl down into said hay vertically; and, at the saine time, the rope E is wound around the said roller. When the fork has been properly adjusted in the hay, the leve;` stop il is moved towards the said roller to prevent the hay from being discharged from the fork too soon, as heforedescribeu. When the loaded fork has'renehed the desired position, by pulling upon the rope E, the lever stop H is drawn back, and the i roller D revolved, turning the spiral tine F out of the hay, and allowing the said hay to drop from the fork. .if the spiral tine F is made with an inclination of from twenty-iVe to thirty degrees, the weight or pressure of the hay alone will revolve the snidtine, and dischfrge the hay. In this case no more power need be applied to the rope E than enough to draw haelt vthe lever stop H.

What I claiin as new, and desire to secure by Letters Patent, is The vertical tines A, shank B, roller or pulley D, and one or morc'splral tiues F, in combination with the rope E, support G, lever stop H, and spring I, substantially as described for the purpose specified. The above specification of i'ny invention signed by nie this 25th day of September, lSlit.
